Application August 25, 1954, Serial No. 451,998
1 Claim. (Cl. 206-58) This invention relates to miscellaneous products and more particularly to those prepared in a sheet-retaining package or sheets in bulk such as business machine tape, toilet tissue and the like, prepared in rolls, stacks or the like type of package from which portions are removed as they are needed for use.
Specifically the invention relates to a roll or mass of material in sheet form such as paper held together in such a manner that sheets may be individually removed from the mass While the remainder will be kept together against accidental and undesired separation and scattering thereby discouraging untidiness due to scattering of the paper.
Toilet tissues have been prepared in rolls, packages and the like. However, after the wrapper is broken and use has begun, ordinarily there is nothing to prevent the unwinding or unfolding of the tissue by the wind, or by children, pets, and the like, resulting in the scattering of paper and untdiness wherever found.
It is an object of the invention to overcome the above disadvantages and to provide simple inexpensive means for securing usable tissue whether in a roll or flat so that it will not be wasted regardless of whether the roll or bundle is on its end, its side, or in other physical position.
Another object of the invention is to provide means for securely holding together sheet material, such as tissue in a roll or stack whether continuous or of individual pieces and folded separately or interfolded, so that it will not readily separate before or after it is placed in use.
Other objects and advantages of the invention will be apparent from the following description taken in conjunction with the accompanying drawing wherein:
Fig. 1 is a perspective of a roll of sheet material such as addng machine tape, toilet tissue, or the like with a strip of adhesive extending from the center to its circumference and illustrating one application -of the invention;
Fig. 2, a similar view with the adhesive strip appled in spaced segments between the center and the cincumference of a roll of sheet material;
Fig. 3, a similar view illustrating the joining of the edges of the material by an indentation extending from the center to the circumference;
Fig. 4, a perspective similar to that of Figs. l and 3 but with the adhesive strip personalized or in the form of a definite design;
Fig. 5, a side elevation of a pack or stack of interfolded sheets for use for any desired purpose and having spaced adhesive connecting strips;
Fig. 6, a similar view with segmental adhesive connecting strips, it being understood that sheets in a pack or stack may be connected in any of the ways indicated in Figs. 1 to 4.
Briefiy stated, the invention comprises the application to a roll, pack, or stack, of sheets of paper or other material of a connection between the sheets to hold them to- United States Patent O M posed n staggered relation and forming a continuous connection from edge to edge ofthe sheets, or by the use of an indentation appled under heat and pressure or in other desired manner, permitting the sheets to be removed' one by one and preventing accidental separation of the sheets and discouraging removal of the sheets merely for the pleasure aiforded.
With continued reference to the drawing, a roll of sheet material of conventonal character includes a tubular core 10 and sheets 11 wound upon said core to provide a roll of the desired size. Thereafter adhesive in the form of a strip 12 is appled either in liqud or solid form. If liquid is appled it will penetrate an infinitesimal amount into the edges of the sheets and hold them securely in place. If a preformed adhesive strip is appled the same result will be accomplished. After the adhesive is appled the sheets may be easily unwound and detached, the adhesive only ofiering sufficient resistance to prevent accidental unwinding or detachment of portions from the roll.
The adhesive is disclosed in Fig. 1 as appled radially since the radius is the shortest distance from the core to the circurnference and minimum adhesive will be required. However, the amount of adhesive employed is so Small that the quantity is almost negligible and consequently it is not necessary to exert care to apply the adhesive along an exact radius.
It may be preferred to apply the adhesive in segments and in Fig. 2 a series of such adhesive segments 13 are employed and they are disposed progressively across the edges of the sheets between the core and the circumference of the roll With slight overlapping so that the revolutions on the roll will at all times be hel d in place. This application of adhesive may be employed where it is preferred to have the adhesive drop off in small pieces as the roll is being used rather than to have the adhesive left in a radial strip after the roll is consumed.
As disclosed in Fig. 3, instead of using adhesive, a groove or indentation 14 may be made by the application of heat and pressure particularly in solidly wound rolls such as are employed on adding machines. If desired, adhesive may be added to the groove but When it is not added there will be no waste When the strip is used.
If desired, instead of a straight adhesive strip or straight indentation or groove as 'disclosed in Fig. 3, the rolls may be personalized, identified, or used for advertising, by employing connecting adhesive or identifying means in some desired form such as a name 15.
The present invention not only is directed to sheets in rolled condtion but contemplates sheets in stacked or edge to edge relation, whether interfolded or not. In Figs. 5 and 6 are shown stacks of flat sheets 16 with connecting portions 17 and 18 either of which may include adhesive appled to the depression. Sheets of this character frequently are used as napkins, towels and the like.
It will be apparent from the foregoing that the present invention is a practical and economical Solution of the problem of maintaining sheets n assembled or group relation so that they will not be scattered by the wind, pets, or children, or by merely being brushed by Clothing. Further the addition of the securing means provides no interference with the use of the material and the additional expense involved is not material.
It will be obvious to those skilled in the art that various changes may be made in the invention without departing from the spirit and scope thereof and therefore the invention is not limited by that which is illustrated in the Patented Feb. 5, 1957* The connection may be in v 3 4 drawing and described. n the specficaton, but Only as References Cited n the file of 'this patent indicated in the accompanying claim.
